HARTFORD, CT — In front of a sold-out crowd at the Connecticut Convention Center, CES Boxing delivered a night of high drama, brutal knockouts, and emotional moments at The Riverside Rumble—a 10-fight card that will be remembered as one of the promotion’s most unforgettable events.

From a shocking main event knockout to breakout performances and a hometown statement finish, the night had everything fight fans crave.

Rowin Sanchez Shocks Jacob Marrero in Dramatic Main Event KO

The headline bout between Bridgeport’s Jacob “Lefty” Marrero (11-1, 8 KOs) and Venezuela’s Rowin Sanchez (7-2-3, 5 KOs) turned into a stunning and emotional finish.

Early on, Marrero appeared in control—mixing sharp offense with disciplined defense while feeding off the hometown energy. In round one, he even dropped Sanchez with a counter left hand, though the referee ruled it an illegal shot to the back of the head.

Momentum stayed with Marrero through round two.

But everything changed late in round three.

During a heated exchange, Sanchez landed a perfectly timed right hook that sent Marrero crashing to the canvas. The referee immediately waved off the count at 2:54 of the round, signaling a knockout victory.

The arena fell silent as medical personnel rushed in. Marrero was stretchered out but was responsive and moving—an encouraging sign following the frightening scene.

With the win, Sanchez captured the WBC FECARBOX Lightweight Championship, capping a life-changing victory after a long and difficult journey to continue his career.

Iman Lee Captures First Title in War with Jose Nunez Sosa

In the co-main event, Iman Lee (15-0-1, 8 KOs) delivered a career-best performance to claim the NABF Super Featherweight Championship with a hard-fought decision over Jose Nunez Sosa (8-3, 6 KOs).

The fight was a relentless back-and-forth battle from the opening bell. Lee used his reach and jab to control distance, while Sosa answered with explosive combinations in close.

As the fight wore on, Lee’s conditioning and composure became the difference.

He surged in the later rounds, earning a well-deserved decision with scores of 78-74, 78-74, and 77-75, securing his first professional title in convincing fashion.

Jose Rivera Upsets Bohdziewicz in Connecticut Showdown

Local bragging rights were on the line in a light heavyweight clash between Jose Carlos “Rated R” Rivera (10-4-1, 5 KOs) and previously unbeaten Slawomir Bohdziewicz (7-1, 6 KOs)—and it delivered.

Rivera set the tone early, scoring a flash knockdown in round one before dropping Bohdziewicz again in round two with a powerful combination.

Despite Bohdziewicz’s relentless pressure and late rally, Rivera’s early success proved decisive.

After eight rounds, Rivera earned a majority decision victory (59-53, 57-55, 56-56) in a gritty, fan-friendly battle that could easily warrant a rematch.

Mykquan Williams Lights Up Hartford with First-Round KO

Hartford’s own Mykquan Williams (24-1-2, 12 KOs) delivered one of the night’s most explosive moments in his long-awaited homecoming.

Fighting in front of his hometown crowd for the first time in four years, Williams needed less than two minutes to make a statement—flattening Argentina’s Guillermo Crocco (20-7-1, 6 KOs) with a devastating overhand right in the first round.

It was a highlight-reel knockout that instantly reestablished Williams as a serious contender in the super lightweight division.
